Design Load Cases - Aircraft fuselage structure Tensile/fatigue loads Static ground loads Shear/fatigue loads

Design Load Cases – Aircraft Structure Dynamic loads – Oscillation of aircraft FLUTTER VIDEO component caused by the interaction of https://www.youtube.com/w atch?feature=player_detailpa aerodynamic forces, ge&v=iTFZNrTYp3k structural elastic reactions, and inertia

Design Load Cases - Flutter Dynamic loads – Design for damping properties of structures needed

Spacecraft Structure Gravity Handling and transportation loads – Vibration and acoustic test loads Launch loads (static & dynamic) Quasi-static – Sine vibration – Acoustic noise and random vibration – Shock loads – In-orbit loads Shocks – Structurally transmitted loads – Internal pressure – Thermal stress –

Spacecraft Structure Steady state load – Axial: launch vehicle engine trust – Lateral: wind gust & vehicle maneuvers
